Vanessa Lachey left newborn son Camden John at home for a night out with her ladies.

The stylish brunette, who enjoyed dinner with hubby Nick at Mastros Steakhouse in Beverly Hills, left the restaurant joking with her gal pals. Such a bummer Nick had to leave early. But Mrs. Lachey is lookin' fabulous!

Camden was born on September 12, and his mama is already rocking her sexy heels. You go, girl!
